Background technique

[0002] "Cold chain logistics" refers to a systematic project in which frozen and frozen foods are always in a prescribed low temperature environment during production, storage, transportation, sales and consumption to ensure food quality and reduce food loss. .

[0003] However, with cold chain cars, it is not always possible to guarantee the refrigeration requirements during transportation. The mature cold chain system has strict temperature standards, coupled with the salary and economic benefits of many cold chain transportation companies. It belongs to the calling vehicle. Individual car owners or drivers need less cooling and air conditioning in order to save transportation costs. Some drivers turn the temperature to a very low level and then turn off the cooling air conditioner to let it cool slowly. In fact, there is a certain temperature and humidity requirement for each fresh-keeping product. China is divided into 7 grades in cold chain transportation. For example, if you transport a banana from the south to the north, the driver will lower the cooling temperature to a low temperature, and then let it cool slowly, which will save trouble and reduce fuel consumption. From the surface, the preservation is very good, and the bananas have actually been made. Frostbite, it will turn black after two or three days. The best storage temperature for bananas, mangoes and other fruits originating in the tropics is generally between 7 ° C and 14 ° C. In the refrigerator, cold damage will occur, causing the skin to become spotted or dark brown, reducing nutrients. It even caused rot. Therefore, there is an urgent need for a separate monitoring of the temperature and humidity of a cold chain or cold chain transport box that can transport different fresh-keeping products on the same platform, so that it can be controlled in the cold of the set temperature and humidity peaks. Chain transportation security remote monitoring system.
